前言种子生活力的高低,是种子品质优劣的重要标志之一。在一般情况下,种子的生活力决定于母株所处的生态环境条件,以及在贮藏期间环境条件的影响。并随贮藏年代的增加,生活力会逐年下降,以至全部丧失生活力,失去农用价值。为了了解新疆棉花不同品种在贮藏期间生活力的变化情况,以提供农业生产实用的可靠科学依据。我们同库尔勒农科所经作室一道搜集了五十年代末和六十、七十、八十年代初,共16个棉花品种(见表1),进行种子生活力的研究和发芽试验。
Preface The level of seed vitality, is one of the important signs of the quality of the seed. In general, the viability of the seed depends on the ecological conditions in which the mother plants are located and on the environmental conditions during storage. And with the increase of storage years, life force will decline year by year, and even lose all vitality, loss of agricultural value. In order to understand the changes of the vitality of different varieties of cotton in Xinjiang during storage, in order to provide practical and reliable scientific basis for agricultural production. We collected 16 cotton cultivars (see Table 1) from the late 1950s, early 1960s, early 1970s and early 1980s together with Korla Ancestral Labs to conduct research on seed viability and germination tests.
